Butterfly
Network
Designing agent-native workflows for Butterfly's pioneering Ultrasound-on-Chip™ platform, reducing time-on-task by 41% while keeping clinicians in control.
Reduction in average review time per study, from 57.2s to 33.6s, after the Compass AI rollout.
Beyond Imaging
Designing workflows that move handheld ultrasound from image capture to AI-powered clinical decision support.
Mobile to Cloud
Hundreds of refinements optimizing how clinicians use the product every day.
Expert time, at scale.
Butterfly helped redefine ultrasound: a handheld, whole-body imaging system built on semiconductor technology rather than traditional cart-based hardware. But as point-of-care ultrasound scaled, a new bottleneck emerged: expert review.
Quality assurance was consuming clinician time already in short supply. The challenge was not simply to make review faster. It was to protect expert attention, keeping clinicians focused on diagnostic judgment rather than repetitive navigation, scoring, and documentation.
Augment the expert, don't replace them.
We did not add an AI layer on top of the existing workflow. We redesigned the reviewer experience around Compass AI: a set of agent-assisted tools that prepare, prioritize, and structure the work before the clinician enters the loop.
The clinician stays in control. The system reduces the blank-page problem, surfaces what matters, and turns review from manual assembly into expert validation.

What We Designed
Guided InterfaceA Guided, Intelligent Interface
Structured cues replace blank forms, while Compass Sort and intelligent cine highlighting surface the frames that matter. The system prepares the work and reduces scrubbing through long loops, so clinicians move faster while staying fully in control.
Mobile ExperienceMobile Experience
Series of mobile app improvements, each resolving the deep edge cases clinicians hit in everyday use, adding up to a calmer, more predictable experience right on the device.
DocumentationDocumentation that Listens
Voice-driven documentation reduces the friction of manual entry. Clinicians can capture feedback naturally, while the agent structures and refines it into usable documentation for review.
Performance DashboardProgram Performance Dashboard
A centralized view of imaging volume, compliance, review status, and revenue opportunity, giving teams visibility across the POCUS program, not just individual studies.
Fleet ManagementFleet Management
We redesigned device oversight from scattered metadata into an operational workflow. Admins can identify inactive, lost, stolen, or failing devices, inspect scan history, and understand fleet health without leaving the core Cloud experience.
A System, Not Screens
Across mobile and Cloud, we improved the everyday workflows that hold the platform together (presets, protocols, favorites, QA, onboarding, and release communication), making complex clinical tooling easier to operate at scale.
The work is under wraps. The impact isn’t.
Much of what we designed for Butterfly is still in development, where exposing the details would reveal the next generation of the product before launch. What we can share is how Butterfly’s product, design, and engineering leaders describe the partnership.
“Working with the Mirumee team has felt more like a true partnership than a standard agency engagement. They have integrated well into our design workflows, tackling complex clinical UX projects with ease. Their collaborative approach and willingness to explore multiple design directions have made them a dependable resource for Butterfly.”
Adam Meisel
Head of Design at Butterfly Network
“Designing for a medical device requires a specific mindset, and Mirumee totally gets it. They understood the hardware constraints and streamlined our user experience, seamlessly integrating AI capabilities to help clinicians work faster and with greater confidence.”
Calvin Solomon
Product Manager, Clinical Experience at Butterfly Network
“Mirumee's designers have the impressive ability to navigate complex medical workflows while also considering the small but critical details that reduce clicks, minimize friction, and eliminate user confusion. The onboarding time for the designers was virtually nonexistent, as they quickly intuited the challenges our end users face — not only within our specific product, but across the broader healthcare industry. The final designs are intuitive, functional, and visually polished. I would highly recommend Mirumee to any organization seeking a thoughtful, collaborative, and highly capable design partner in the MedTech space.”
Bridget Gonyeau
Product Manager at Butterfly Network
“The design team from Mirumee has been outstanding to work with. We built a complex medical application with real technical constraints, and they navigated that environment like true partners, designing thoughtfully for both users and developers. They went beyond the ask, helping solidify our design system and bringing our Figma documentation up to a standard we hadn't seen before — well-maintained, edge cases included. I'd recommend them without hesitation.”
Patrick Powers
Director, Mobile Engineering at Butterfly Network
The work of democratising medical imaging is an ongoing mission. We’re currently in the lab with the Butterfly team, refining the next generation of features across the entire product suite — from the Global Store to Cloud PACS and the Mobile App. Ready to reveal soon.
